The objective of the project was to develop a numerical model than may be used to predict the wrinkle formation and post formation behavior of a pipeline considering the effect of soil confinement and define the specifications for the development of…
Severe problems with wrinkling when making field bends in ERW pipe coated with a fusion-bonded thin-film coating have been reported by several PRCI member companies in recent years. When these problems were encountered, wrinkling was controlled by…
